Using exifReader in AWS S3 Lambda about exifreader HOT 2 CLOSED

Hi,

I was facing the same issue. Most likely you are not reading the files correctly and Exif is failing silently.

Doing this fixed it for me

var files = e.target.files; // This is basically the filelist object. 
for ( file of files) {
    let reader = new FileReader();
    reader.onload =  function (readerEvent) {
       try {
	      let tags =  ExifReader.load(readerEvent.target.result);
	      coordinates_array.push( { 'lat':tags['GPSLatitude'].description, 'lng':tags['GPSLongitude'].description } );
                // After getting the coordinates delete tags as it can have a huge memory imprint.
		delete tags;

	} catch (error) {
			console.log("EXIF failed: ", error);
	}
     };
	  reader.readAsArrayBuffer( file );
}

@sudhar99 I think this is your issue: When using expanded: true the result comes back segmented into file, exif and xmp properties like this: {"file": {...file tags...}, "exif": {...exif tags...}, "xmp": {...xmp tags...}}. Your loop tries to get the description on the wrong object, you have to go one step deeper in the structure. If you're only interested in the XMP data, change to this and it should work: listTags(exifData.xmp);
